Structure Formation of Bio-Elements
Advances in Bioengineering and Biomedical Science Research, 2022 We study a Nano-Structural 4-forces of New Atomic Model, a lithography of biological elements on the basis of Super Unified Theorem SU(11)⊃SU(6)×SU(5)×U(1) or SU(11)⊃SU(6)×SU(3)×SU(2)×U(1). The existences of up-converting quantum masses or positions or dots of colloidal lithographies from exotic matter fluid to ordinary matter through colloidal stages,

Primordial Fluctuations From Quantum Gravity
Frontiers in Astronomy and Space Sciences, 2021 We study the fluctuations and the correlations between spatial regions generated in the primordial quantum gravitational era of the universe. We point out that these can be computed using the Lorentzian dynamics defined by the Loop Quantum Gravity ...

Modification of portland cement with nanoadditives [PDF]
Нанотехнологии в строительстве, 2022 : Introduction. Portland cement slurries (suspensions) used for well cementing have high water-cement ratios (0.45–0.6). They also contain a minimum amount of inert fillers, must have zero water separation and controlled hardening with a minimum time

Cosmic structure formation [PDF]
Physica D: Nonlinear Phenomena, 1994 This article reviews the prevailing paradigm for how galaxies and larger structures formed in the universe: gravitational instability. Basic observational facts are summarized to motivate the standard cosmological framework underlying most detailed investigations of structure formation.

Density perturbations for running vacuum: a successful approach to structure formation and to the σ8-tension [PDF]
, 2018 Recent studies suggest that dynamical dark energy (DDE) provides a better fit to the rising affluence of modern cosmological observations than the concordance model ($\Lambda$CDM) with a rigid cosmological constant, $\Lambda$.

Constrained coalition formation
, 2011 The conventional model of coalition formation considers every possible subset of agents as a potential coalition. However, in many real-world applications, there are inherent constraints on feasible coalitions: for instance, certain agents may be ...

Cosmic confusion and structure formation [PDF]
Physical Review D, 1996 We present a re-analysis of the cosmic confusion hypothesis, elucidating the degree to which ``confusion'' can be expected to hold in a class of flat, adiabatic models. This allows us to devise a simple and accurate fitting function for the height of the first peak in the radiation power spectrum in a wide range of inflationary inspired models.

Unveiling carbon ring structure formation mechanisms in polyacrylonitrile-derived carbon fibers.
ACS Applied Materials and Interfaces, 2019 As the demand for electric vehicles (EVs) and autonomous vehicles (AVs) rapidly grows, lower-cost, lighter, and stronger carbon fibers (CFs) are urgently needed to respond to consumers' call for greater EV traveling range and stronger safety structures ...

Machine learning cosmological structure formation [PDF]
Monthly notices of the Royal Astronomical Society, 2018 We train a machine learning algorithm to learn cosmological structure formation from N-body simulations.
